I'm not GP, but I have backups, plus I always make sure I've committed and pushed all code I care about to the remote. I do this even when running a prompt in an agent. That goes for running most things actually, not just CC. If claude code runs a git push -f then that could really hurt, but I have enough confidence from working with the agents that they aren't going to do that that it's worth it to me to take the risk in exchange for the convenience of using the agent.

I don’t even trust myself to not mess up my git repo

If that's something you're worried about, review the code before running it.

I think you might want to not run untrusted programs in an environment like that, alternatively find a way of start being able to trust the program. Either approaches work, and works best depending on what you're trying to do.

I push my branches daily, so I wouldn't lose that much work. If it breaks then I ask it to fix it.

But I do quickly check the output what it does, and especially the commands it runs. Sometimes it throws all code in a single file, so I ask for 'good architecture with abstractions'.

Isn't it this case no matter who wrote the code? How do you ever run anything if you're worried about bugs?

I assume that whatever I type can be also flawed and take precautions like backups etc

It's a git repo. What's sort of mess-ups are you worried about that you can't reflog your way out of (or ask claude code to fix)? It's certainly possible to lose uncommitted work, but once it's been committed, unless claude code goes and deletes .git entirely (which I've had codex do, so you'd better push it somewhere), you can't lose work.
